Laboratory ventilation types
Laboratory ventilation system and air quality are usually one of the most difficult tasks for laboratory construction companies in their laboratory planning. Although air quality may have a direct (and unnecessary) impact on any laboratory discussion, all members of the research team should have an active working environment.
There are two main ventilation modes in research facilities and commercial laboratories: natural ventilation and mechanical ventilation, which help to reduce containers in different environments.
Relying on wind pressure, the research laboratory filled with fresh air is pumped into the vent. Natural ventilation is affected by wind speed, direction and building shape. Natural ventilation is difficult to control and handle - if doors and windows are closed, air will become blocked.
Cooler air entering the lower floors rises and escapes through roof vents or high-rise windows. This process is more environmentally friendly than mechanical ventilation and has lower operating costs, but it also makes the workplace vulnerable to environmental impact.
Mechanical ventilation, such as air conditioning equipment, can assist in controlling the temperature and quality of air entering the laboratory. These systems can be used to control humidity and overall environmental comfort.
Mechanical ventilation can be more tightly controlled than natural ventilation, but it is unlikely to eliminate all pollutants in the air. This means that the laboratory may need additional fresh air to pump the air into the environment to keep the research team healthy.
In order to accurately provide adequate air supply for the laboratory research team, it is important to consider building area, operational activities and air pollutants. The latter is particularly important when dealing with potentially hazardous information and chemicals in the laboratory. When planning a laboratory ventilation system, all short-term and long-term operations in the environment should be taken into account.
